If you use Sleep Mode on your PC, have you ever noticed that moving your mouse will wake the computer from sleep mode? If you would prefer to only have the PC wake up when you hit a key instead, there’s a simple tweak.

Just type Mouse into the start menu search box, or the Control Panel search box, and then open up the Mouse Properties panel. Find the Hardware tab, select your mouse in the list, and then click the Properties button.

You’ll have to click the “Change settings” button before you can see the Power Management tab…

And now, you can uncheck the box from “Allow this device to wake the computer”.

That’s all there is to it.
